DC Motor, How it works?

The operating of a DC motor is effectively described in this movie with the aid of animation. Building details of DC Motor, Shunt & Series motor, principle of back EMF are also described in this video.

good video but should the positive and negative connector be changed? the north magnet is attracted to the positive side(because positive is south) and the south magnet is attracted to the negative (Because negative is north).

I dont think this DC motoro will work unless you switch the terminals.﻿

please upload more videos.They r awesome﻿

should the armature be spinning the other way? by the right hand rule the side with the current going away should have moved up, not down?﻿

that was very nice﻿

thank u for your explanation﻿

This is a fucking gift﻿

SabrinaOctober 1, 2015 at 3:17 pm

Thank you very much. You are real guru in the electrical machinary. Your awesome video helped me understand & remember these knowledge easily﻿

good work.﻿

In the DC motor, do axles on both sides of the motor spin, or only 1 side? When I buy generic motors, only 1 axles is exposed and moving. Would love it so that axles stuck out both sides of the motor!﻿

Hard to believe somebody that can make their own voltmeter would stop a saw blade with their hand﻿

I watched a video on youtube, It said that "when you put a loop with a current through it (DC current) in the permanent magnet, the rotor start to rotate because of the torque, based on the lorent law" but in this video, you say rotor rotate because the two poles of magnet of stator attract the two poles of coil, This problem make me feel quite confused, please help! Tks you and love you!﻿

thanks you very much! it's understandable much more the other videos I watched﻿

i couldn't be more fascinated. great video. are all induction motors brushless?﻿

cepsonOctober 1, 2015 at 9:08 pm

Very nice. Simple, yet instructive.﻿

I have been watching every other video hosted by engineers with fancy animations explaining how the motors work and your video is the best by far. Thank, I know I will pass my electrical test tomorrow﻿

Andrês SantanaOctober 1, 2015 at 10:08 pm

really nice video!﻿

If the whole idea is to magnetise the copper core then why not attach the to wires to the two sides of the magnet? Or why not just put another magnet inside the motor?﻿

shan alviOctober 1, 2015 at 11:28 pm

Pleace make a video on how you make voltage regulator﻿

rovannonOctober 2, 2015 at 12:27 am

I like your stuff but man you are a bit creepy:)))))﻿

James James (BuyAussie)October 2, 2015 at 12:54 am

very nice explanation. thanks!﻿

You are just good for your explanation. Very easy to understand.Thanks a lot.﻿

Telmo MonteiroOctober 2, 2015 at 1:10 am

You do explain things well! This is good stuff! Thank you!﻿

Will MerrittOctober 2, 2015 at 1:46 am

I know this is a old video but my question is what actually goes on when you want to run the motor in reverse?﻿
